SPARK=ARRESTER.

SPECIFICATION forming part of Letters Patent No. 369,483, dated September 6, 1887.

Application filed February 15, 1887. Serial No. 22 705.

To all whom it may concern."

Be it known that I, JAMES M. O. TYNER, a citizen of the United States of America, residing at Ellendale, in the county of Dickey and Territory of Dakota, have invented certain new and useful Improvements in Spark- Arrcstcrs for Steam-Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in sparknrresters for steam-engines; and it consists in certain novel featuresof construction, which will first be described in connection with the accompanying drawings and then pointed out in the claims.

Figure 1 of the drawings is a vertical sectional view of the smoke-stack and its head with the arrcster in place. Fig. 2 is a perspective view of the arrester. Fig. 3 is a detail View.

Referring to the drawings, A represents the smoke stack, and B its head, of any ordinary form, but preferably of the form shown, which is riveted to the stack considerably below the upper end of the latter-that is to say, the stack extends some distance up into the headfor a purpose which will hereinafter appear. A short outiet'pipe, O, communicates with the interior of the head at a point as near as possible to the junction of the latter with the smoke-stack, and is provided on either side with a short pin, a.

D represents a conduit-pipe slotted at its upper end, as shown at d, adapting it to be secured over the outletpipe by a bayonetjoint, and provided atits lower end with short pins d similar to those on pipe 0.

E represents a cap to fit over and close the lower end of the conduit-pipe, it being also slotted, as at c, for attachment by bayonetjoint.

Inside of head B, a.- short distance above the top of stack A, is a series of lugs, b, for supporting the spark'arrester, which arrester will now be described.

F represents an inverted cone made of wirecloth. The base of this cone is secured between two annular plates, G- G, t the latter, G, having a downwardly-extending flange, g,) and its apex is covered by a metallic cap, H. Metallic braces I, secured to the cap and to (No model.)

the under side of plate G, serve to support the cone and keep it in shape, and the meeting edges of the wire-cloth forming the cone are secured by means of a metallic strip, J, the sides of which are folded over the edges of the cloth, as clearly shown in Fig. 1..

K represents a downwardlyextending and outwardly-flaring wire-cloth apron of a size at its bottom to fit the interior of head 13. The upper end of this apron, also, is secured between plates GG, which are clamped together by screws. The apron is held in shape by the rim on plate G, and by a metallic hoop, L, at its bottom, to both of which it is secured, and also by metallic braces M,secured to the hoop and to plate G.

N represents springs, made of any suitable metal, secured at their upper ends to the plate G, while their lower ends are hooked under hoop L, which allows them to yield when putting the arrcster in place in the head.

When the spark-arrestcr is in placcin head B, the hoop of the apron rests on lugs b, the apex of the cone extends down into the top of stack A, and springs N impinge against the inner side of the head with sufficient force to hold the arrcster in place. Thus it will be seen that while the arrestcr is amply secured when in use, it may be readily and easily removed when desired. \Vhile the engineisin operation, the sparks and ciuders are thrown up against the cone and byitdetlected against the apron, which in turn directs tllem down into the annular space between the stack and the bottom portion of the head, whence they pass out at the outlet and are conveyed away by the conduit. \Vhen the engine is not in use, the conduit may be detached and its cap used to cover the outlet-pipe.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. The combination, with the smoke-stack and thehead, the former extending up into the latter, which is provided with lugs on its inner side, of a removable spark-arrcster consisting of an inverted wire-cloth cone secured at its base between annular plates, a down wardly-extending and outwardly-flaring wirecloth apron secured at its top between said plates, the bottom of the apron fitting the interior ofthehead and resting on the lugs, and laterally-acting springs for securing the arrester in place, substantially as described.

2. The combination, with the smoke-stack and the head, the former extending up into the latter, which is provided with lugs 011 its inner side above the top of the stack, and an outlet at the junction of the stack and head, a conduit removably attached to the outlet, and a removable cap for the conduit, of an inverted wire-cloth cone whose apex extends into the stack and whose base is secured between annular plates, a downwardly extending and outwardly-flaring wire-cloth apron secured at its top between said plates, the bot- 15 apron, substantially as described, and for the 20 purposes set forth.

In testimony whereof I hereunto afiix my sigv nature in presence of two witnesses.

JAMES M. G. TYNER.
